INLS 180 Day 3 Notes

Feb. 6, 2006

 

Reminder: question assignment due next monday

 

  1. One minute papers

Points

Information is reduction in uncertainty

Message detection and correction combination of coding and human inferencing

We develop noise filters

Rumors/distortions show how interaction changes info

Rumors as viral infections

Need for homeostasis and information diets

 

Questions

How do noise filters vary across demographics?

Effects of cell phones (and DLs) on our info processing/memory abilities (Socrates revisited)

Frey’s book (million pieces) changed depending on whether you read before or after Oprah part 2?

How is the scale of e-info changing me (e.g., personality, anxiety, behavior, etc.)?

Several questions about ‘semantics’ and the meaning of meaning

Common interest more essential than a common language??

How does any of this apply?

What is the bit rate of ftf communication?

In logging my click streams communication?  [no, interaction]

Is homeostasis innate or learned?

 

  1. Project ideas

 

  1. Rogers’ theory of diffusion of innovation (see slides)
    1. Why is this important?

                                                               i.      Social and economic change

                                                             ii.      Spread of ideas and information

                                                            iii.      Tipping points

    1. Rogers’ approach

                                                               i.      Case studies (e.g., boiling water, Scurvy, QWERTY)

                                                             ii.      Theory of individual and social behavior (social psychology)

    1. Key ideas

                                                               i.      Personal adoption: awareness/knowledge; persuasion; decision making; implementation; reflection/confirmation

                                                             ii.      4 key factors: innovation/idea; communication channel; time; social system

                                                            iii.      Adoption curve (bell curve with time by number of adopters); innovators (2.5%, i.e, 2 standard deviations), early adopters (13.5%, 1 SD) who tend to include the opinion leaders; early majority (34%); late majority (34%); and laggards (16%).  The curve is a logistic (S curve) if we plot proportion of adoption over time
